If you want a garden record that survives more than one season, GardenOS is the pick: one offline HTML file, $23 once, and your beds, sowings, harvests and notes stay on your own device with no account and no renewal. If you want the software to calculate your sowing schedule for you, Seedtime does that better. If you want to drag beds and plants around a visual layout with crop rotation warnings, GrowVeg does that better.

1. GardenOS - best for the garden history that makes next year better
A garden plan is nearly worthless without last year’s notes. The plan tells you what you intend to do; the notes tell you what actually happened - that the Romas went in too early and sulked, that the fall lettuce bolted in the bed that gets late sun, that the first real frost hit your yard almost two weeks after the date the app predicted. That record is the part that compounds. It is also the part most likely to be sitting behind a lapsed subscription.
GardenOS is one HTML file you download and open in your browser. It covers beds, crops, timing and results:
- Beds - every raised bed, row or container with name, size, sun exposure (full, part, shade), soil notes, current crops and sow dates.
- Plant library - 40+ pre-loaded varieties (Tomato Roma, Basil Genovese, Carrot Nantes, Lettuce Butterhead, Zinnia, Marigold and more) with days to maturity, preferred sun, and companion and avoid lists.
- Calendar - an auto-generated 12-month sow, transplant and harvest schedule built from your planting dates plus each variety’s days to maturity, with colored markers for sow, transplant, harvest and frost.
- Harvest log - yields by variety and bed with rolling season totals in lbs, count, bunches, quarts, oz or kg. This is the number that tells you whether the bed earned its space.
- Soil and amendments - per-bed log of compost, manure, lime, bone meal or worm castings with pH and an auto-calculated next-due date, plus a compost pile tracker with turns and ready date.
- Dashboard - this week’s sow, transplant, harvest and amend tasks, plus a days-to-frost countdown.
It is $23 one-time. No subscription, no account, no cloud, no login. Everything you type is saved on your own device only, it works fully offline after the first load, and there is an export button so you can move your seasons somewhere else whenever you want. It runs on a laptop and can be added to your home screen on iPhone (Safari) or Android (Chrome).
Where it loses. You enter your USDA zone and frost dates yourself in Settings - GardenOS does not look them up from your location, and the dedicated apps below do. It is not a visual drag-and-drop bed designer either; beds are records with dimensions and notes, not shapes you push around a grid. There is no community, no plant ID from photos, no push notifications, and no AI. If any of those are the reason you want an app, buy one of the others instead.
2. Seedtime - best for sowing schedules and succession planting
Seedtime builds your planting calendar around your location and your crops, and it is genuinely good at the timing problem: when to start seeds indoors, when to transplant, when to sow the next round so you are not harvesting all your beans in one week. The free-forever tier is real - one calendar with built-in crops, plus unlimited tasks, journal entries and planting schedules - which is more than most free tiers give you. Paid plans (Basic and Unlimited) are billed monthly or yearly and add unlimited calendars, custom crops, garden layout tools and inventory tracking, with a 7-day trial and a 30-day money-back guarantee.
Where it loses. It is an account-based web and mobile product, so it needs a connection and your records live on their servers. The layout tools, custom crops and extra calendars sit behind the paid tiers, and the yearly cost of the top plan is several times the price of a file you buy once. If you want succession timing computed for you, that trade may be worth it. If you mainly want a durable journal, you are renting the wrong thing.
3. Planter - best for planning beds on your phone
Planter is mobile-first and it shows: laying out a square-foot bed and tapping in plants feels natural on a phone in the garden, which is exactly where you actually make these decisions. It carries a large catalog of vegetables, fruits and flowers with local planting times, companion and combatant plants, and notes on diseases and pests. The free tier covers one garden with the growing calendar, custom plants and seed box. Premium is $24.99/year and adds unlimited gardens, no ads, notes and events, custom backgrounds and the web app. There is also a $99.99 lifetime license, which is the honest option for anyone who hates renewals.
Where it loses. The free tier’s one-garden cap gets tight fast if you have several beds or a plot plus containers. Notes and events - the journal part - are premium, so the record you most want to keep across years is the thing you pay for. It is an account-based app rather than a file you hold.
4. From Seed to Spoon - best for first-year gardeners
From Seed to Spoon is the friendliest of the group for someone who has never grown anything. It is free to use, gives you a visual garden layout, and calculates planting dates from your GPS location within the United States, with companion planting warnings when you put quarrelsome plants next to each other. If you garden outside the US, or you know your yard runs later than the prediction, you can set custom frost dates in settings. The paid Garden+ tier adds plant tracking, sprouting and harvest estimates, weather info, garden log and archive, notes, photos, unlimited beds and plants, and personalized notifications.
Where it loses. The genuinely useful long-term features - the garden log, the archive, photos, unlimited beds - are the premium ones, so the free version is closer to a growing guide than a record system. Pricing for Garden+ is not clearly published on the site, so check it in the app before you commit. Like the others here, it is account-based.
5. GrowVeg - best for visual layout and crop rotation
GrowVeg (the same planner behind the Almanac Garden Planner) is the veteran. You draw beds to scale, drop in crops, and it handles spacing for you and color-codes crop rotation so you do not plant the same family in the same soil three years running. It sends email reminders for sowing and planting, lets you copy last year’s layout into next year, and includes support from gardening staff. There is a 7-day free trial with no card required, and the auto-recurring annual subscription runs about $35/year (non-recurring one-year and two-year options cost more).
Where it loses. It is a subscription with no lifetime option and no free tier once the trial ends, and it is browser-based, so no connection means no plan. Your plans live in their account. If you drift away for a season and come back, you are paying again to look at your own history. The design tool is excellent; the ownership model is a rental.
6. Amazon seeds and tools - best for the part software cannot do
No app germinates anything. The physical layer - seeds, seed-starting trays and domes, a heat mat, a grow light for leggy indoor starts, a soil thermometer so you sow by soil temperature instead of the calendar, and plant labels you can actually still read in August - is where Amazon is useful. These are one-time purchases, not subscriptions. A soil thermometer in particular does more for germination rates than any planning feature on this page, because soil temperature is what the seed responds to.
Where it loses. It is a store, not a planner. It will not tell you when to sow, and it will not remember what you did.
How to choose
- Pick GardenOS if you want your beds, harvest totals and season notes in a file you own, offline and private, for $23 once with nothing to renew.
- Pick Seedtime if you want sowing and succession dates computed for you and you are fine paying yearly for it.
- Pick Planter if you plan from your phone in the garden and want a one-time lifetime license rather than a subscription.
- Pick From Seed to Spoon if this is your first year and you want plant-by-plant guidance and location-based dates for free.
- Pick GrowVeg if drawing an accurate scale layout with crop rotation warnings is the main job you are hiring software for.
What to write down in year one
Whatever tool you pick, the notes below are the ones you will want in year three. Most gardeners record none of them and start over every spring.
- Actual frost dates, not predicted ones. Hardiness zones and frost dates vary a lot by location, and your yard can differ from the regional average because of slope, walls and shade. Check your local dates from a reliable source, then log the date frost actually arrived in your garden. After two or three seasons, your own numbers beat any lookup.
- Sow date and the date it emerged. The gap tells you whether your soil was warm enough. It is the fastest fix for “the seeds never came up.”
- What failed, and your best guess why. Failures repeat when they are not written down.
- Harvest weight per bed. It ends arguments about whether the zucchini deserves four square feet.
- Where each family grew. Rotation only works if you can remember three years back.
If you want the rest of the household running the same way, the full Ecuato catalog is built on the same idea: one file, one payment, your data on your device.
Frequently asked questions
What is the best garden planner app?
It depends on what you want the plan to do. GardenOS is the best pick if you want a garden journal and bed record you keep forever, because it is a single offline HTML file you buy once for $23 with no account. Seedtime is stronger for automatic sowing schedules, and GrowVeg is stronger for drag-and-drop bed design with crop rotation warnings.
Is there a free garden planner app?
Yes. Seedtime, Planter and From Seed to Spoon all have free tiers that cover a single garden or calendar, and GrowVeg offers a 7-day free trial. The free tiers usually limit you to one garden layout or one planting calendar, and they gate the visual designer, extra gardens or inventory tracking behind a paid plan.
Do I need a subscription to plan my garden?
No. GardenOS is $23 once with no renewal, and Planter sells a lifetime license alongside its yearly plan. Seedtime and GrowVeg are subscription products, so your access to saved plans depends on continuing to pay.
What happens to my garden notes if I stop paying for a garden app?
On subscription apps, your journal and past seasons usually become read-only or inaccessible when the plan lapses, and free tiers often cap you at one calendar or garden. That is the main reason to keep records in a file you own. GardenOS stores everything in your browser on your own device and has an export button, so your history does not depend on a billing status.
Does GardenOS work offline and is my data private?
Yes to both. GardenOS is one HTML file that runs fully offline after the first load, and everything you type is saved on your own device only. There is no account, no cloud and no server, so Ecuato never receives your garden data.
Does GardenOS look up my frost dates and hardiness zone automatically?
No. You enter your USDA zone and your first and last frost dates yourself in Settings, and the dashboard then counts down to frost from those values. If you want automatic GPS-based frost dates and zone lookup, Seedtime, Planter and From Seed to Spoon do that for you.
Can I use a garden planner on my phone?
Yes. GardenOS opens in a browser on a laptop and can be added to your home screen on iPhone via Safari or Android via Chrome, so it behaves like an app. Planter and From Seed to Spoon are mobile-first apps and feel more native on a phone, but they need an account.
